AT YOUR OWN RISK, you can force the installation of this version of udev
WHICH DOES NOT WORK WITH YOUR RUNNING KERNEL AND WILL BREAK YOUR SYSTEM
AT THE NEXT REBOOT by creating the /etc/udev/kernel-upgrade file.
There is always a safer way to upgrade, do not try this unless you
understand what you are doing!

So i changed to the default kernel of debian, but with this one systems was not able to mount the partitions, because the old kernel mounted the disk on /dev/hda and the new one on /dev/sda.
So i had to rewrite the /etc/fstab and after that, the dist-upgrade could continue...
